Sharing some logic between the cores can make a complex area efficient. This patch adds complex level for complexs by parsing cache topology form DT. It will directly benefit a lot of workload which loves more resources such as memory bandwidth, caches. Note this patch only handle the DT case. wangqing (2): arch_topology: support for describing cache topology from DT arm64: Add complex scheduler level for arm64 arch/arm64/Kconfig | 13 ++++++++++ arch/arm64/kernel/smp.c | 48 ++++++++++++++++++++++++++++++++++- drivers/base/arch_topology.c | 47 +++++++++++++++++++++++++++++++++- include/linux/arch_topology.h | 3 +++ 4 files changed, 109 insertions(+), 2 deletions(-)
